The appended drawing shows by way of eX-4 ample a mode of construction of my invention in which said strap is pivotally fastened to a block engaging in a recess 1n the container.

The strap I passes recess in the bottom of the kind of hinges at these through a lever 3 pivotally connected with the middle portion of the latter which extends over the receptacle. lThe lever 3 is provided with an eccentric head or cam 3ab which is sufficiently short at one side near to allow of separating lever, strap and the pivot the part constituted by the block from the element constituted by the receptacle and its lid and of placing it in position upon sai d element.

respect for securing the (Cl. ZIO-165) The head of the lever is rounded at 3c and engages a senil-spherical cup 5 provided in the plug B of the lid C of the receptacle. As may be clearly seen in the drawing the radius of curvature of the rounded portion 3 of the lever is less than 5 the radius of curvature of the semi-spherical cup 5, whereby the rounded portion is enabled to readily roll or slip in the recess and will come to the position of least resistance. Owing'to this arrangement when the lever is brought from the raised position to that shown in the gure, the strap will swing back but the eccentric will come exactly in the middle of the cup 5 and owing to its eccentricity will strongly press the part 6 and the receptacle against the joint J and the lid. The parts are locked in place in a known man- Y ner by the oblique position of the strap.

It will easily be seen that the operation may be effected almost instantaneously and that owf ing to the centering of the eccentric in the middle of the cup, the pressure will be distributed uniformly around the periphery of the receptacle opening thus ensuring an absolutely tight joint.

The packing J is made for example of pressed cork, the container or receptacle R of glass and the block 6 of metal.

My invention may be utilized for rapidly closing and locking in position all kinds of receptacles and its application to filters has only been used as a preferred example.

It will also be understood that the -steel wire which has a certain elasticity may be replaced by a rigid strap and that if wanted a spring might be used. 3

What I claim and desire to secure by Letters Patent of the United States is:

In a fluid line filter, a head having an inlet and an outlet passage, and havinga central opening communicating with said outlet passage, a receptacle having its upper edge engaging the under side of said head, a plug closing the upper end of the central opening of the head, said plug having a semispherical recess, a yoke encompassing the head and receptacle and pivotally engaging the bottom of the receptacle and having an eccentric spheroid pivoted at its upper portion to engage the recess of the plug, the radius of curvature of the spheroid being less than that of the recess, a lever for operating the spheroid, and a lter suspended from a tube extending downwardly into the receptacle from the central openving of the head.
